ment in Filling-Replenishing Looms, of

which the following description, in comico-- tion with the accompanyingdrawings, is a i specification, like characters on the drawingsrepresenting like parts.

This invention relates to filling replenishing looms and .'inoreparticularly to the means for withdrawing filling from the shuttle eyeafter a replenishing operation.

' In looms of this general type, itis common to rovide means for partingor cutting the filling between the cloth selvage and the Voutgoingfilling carrier or bobhin on call for repliiishinent of filling, andittheend of the l filling leading from the discharged filling carrier orbobbin is not withdrawn from the shuttle ,eyc, it is liable to becaughtlnd carried into the shed.

Numerous devices have been devised haying for their object theaccomplishment of the above purpose and soine of them have electivclyperformed the desired function. The present invention has for itsob]ect. to improve devices,for withdrawing the filling end from theshuttle eye following the replenishing operation and to provide means toeil'c'ctivcly accomplish this purpose, such means being simple inconstruction, effective in operation, and readily applicable to looms ofthis type now in general use.

Various features -of the' invention will best he inadevclear from thefollowing descriptionand accompanying drawings of one good forni ofmechanical means for carrying the invention 'into practical eiiect.

in the drawings: I

Figure l is a perspective view at the .replenishing side of a fillingreplenishing loom some of the parts being broken away for the purpose ofclearness of illustration;

Fig'. 2 is a similar view with sonic of the parts omitted and showingthe. loom elements and associated features in another position.

' in the drawings the loomfraine is shown as of the usual type havingsecured thereto the stand i carrying the-hopper 2 in which are containedthe loaded iillingca-rriers 3.

'Pivotally mounted as'usual on the stand 1 is the transferrer 4f whichserves tn eject the filling carrier or bobhin to be discharged,

and place in the shuttle another filling carrier or bobhin with a freshsupply of filling thereon. The transferrer nia-y be approl priatelyoperated, as well understood by those skilled in the art, and furtherdescription thereof appears unnecessary.

The lay 5, the shuttle box 6, the pickerstick 7, and shuttle 8, are or'may be of any desired and Wellknown: character of construction.

Many of the devices lheretofore provided for, withdrawing the fillingend leading from the discharged lling carrier to the shuttle eye, havebeen of complicated chaiacte i requiring undesirable additions to orauxiliary movements associated with the other loom parts, lout in thepresent invention one of theimportant features consists 1n the simplemeans employed for effecting the withdrawal of the end ofthe fillingfroml the shuttle eye without adding materially to the loom parts or the.auxiliary operation of associated elements.

Secured to the loom frame in any ap r0- priate manner is the bohhinychute 9, w ich may be of any suitable character for directing thefilling carriers or bobbins as they are discharged from the shuttleintoA the receptacle or can 10. In the present nstance the bobbin chute9 is formed of sheet metal or other suitable material and is 'connectedto the loom frame by means of a bracket 1l to which the rear portion ofthe bobhin chute is connected, as indicated in Fig. l.

In the present instance of the invention, the hobbin 'chute 9 -isprovided with a slot 19, leading from its outer edge portion iiiwardlytowardv 'the loom frame and the -l upper wall 13 of the slot thusformed, is providedy `with :i series of roughened edge portions or teeth14, the construction being such that should the filling between the dislcharged filling carrier or bohhin 15 and the shuttle eye be enga-ged bythe roughened edge or toothed portion .14, proj cting downwardly fromthe upper edge o the slot 12, it will be held hy these teeth as theshuttle is picked and thus cause the filling end to he drawn from the.shuttle eye if it has not already been drawn therefrom by th'i'primaryoperation of the device, as vwill presentl appear.

- ishment of filling, such outgoing filling carrier or bobbin may passrearwardly of the thread catcher or linger 16. i f

The thread catcher or finger 16 is located relatively to the slot 12 inthe bobbin chutev 9 so that 'on each beat up'movement of thelay thethread catcher '16 will pass through.

the slot 12 to a osition frontwardly ofi..

bobbin chute.- l hen replenishment of fil 1 ing is effected, theoutgoing filling carrier is discharged from the shuttle when the lay 1sin snbstantiallyits frontward position, and' consequently the threadcatcher 1.6 is in its position frontwardly of the bobbln chute 9,

-the relation of parts being such that the 'discharged filling carrieror bobbin 15, inpassingfrom the shuttle and over 'the bobbin chute 9,will pass over the slot 12 in the bobbin chute and between it and thethrea catcher orfinger 16. 0

As the'lay retreats after; the filling rc-` plenishing operation, thefilling a which has thus been laid between the thread catcher 16 and theslot 12 in the bobbin chute, as indicated in Fig. 1, will be ca ht bythe finger or thread catcher 16 as t e la retreats and a bight'of thefilling threa will be drawn rearwardly through the slot 12 of the bobbinchute, substantially as indicated in Fig. 2. The effect of this is todraw upon the filling vthread betweemthe discharged filling carrier orbobbin 15and the e e of the shuttle, with the result that the llingthread will be withdrawn from the e e of the shuttle by the increasedlength oft read caused by the thread catcher forming the 'bight of thefilling, as indicated at b, Fig. 2. When the filling thread is thusdrawn rearwardly through the slot 12 of the bobbin chute by the threadcatcher or finger 16, the part thereof leading upwardly to the shuttleeye will be engaged by one of the teeth or roughened edge portions 14 atthe lower edge of the upper wall 13 of the slot 12, so that should theend of the filling` not have been wholly withdrawn from the shuttle eyeby the backward movement of the thread catcher or nger 16, as described,the teeth 14 on the lower edge of the upper Y wall 13 of the slot, willsecurely hold the filling as the shuttle is picked after thereplenishing operation, thereby insuring the withdrawal of the fillingthread from the shuttle eye and obviate all possibility of li ountedonthe lay or movable the-'rewith of the filling being' carried into the anoutwardly bowed or bent Qrcast finger,

preferably so curved at its end portion as to retain the bight of thefilling b and prevent it slipping off the end of the 'finger as.

the lay goes back after'a"replenishing operation. he'device issimple,effective, and may. readily be applled tp-a'ny of the socalled'automatic looms now in use, without' material ch`ange or additionsthereto. Claims:A A' j -v 1. Ina filling replenishing loom, the
